IMPROVEMENT IN ADVERT l'SlNG-BRlCKS.

Specification forming part of Letters Patent No. 198,651, dated December25, 1877; application filed November 17,1877.

. or other card or advertisement is placed, so

as to be capable of being read through the top or face of the brick orblock, the said card being secured within said brick or block bysuitable moistureproof material, and the face of the brick or blockbeing protected from abrasion by ribs or beads thereon, so arranged asnot to obscure the advertisement.

In the drawings hereunto annexed, Figure 1 is a perspective view of mybrick or block.

Fig. 2 is a top view, and Fig. 3 is a cross-section on line a; as ofFig. 2.

The letter Aindicates a brick or block of transparent material, asglass, the interior of which from below is hollowed out to form arecess, B, leaving stout sides and ends, and a face, C.

This brick or block is of any desired dimensions; but ordinarily it willbe made of V the size and shape of a common paving or building brick orblock, so as to be capable of being employed in pavements, sidewalks,walls, and the like.

The face 0 is made with a number of ribs or beads, to, to protect itfrom abrasion, and thereby preserve its transparency.

Within the recess B, and up against the under side of the face 0, isplaced a business or other card or advertisement, I), which is printed,painted, or otherwise made, andof any material. This card may be ofpaper or other material liable to defacement by moisture, in which casea suitable water-proof material may be employed as a backing for thecard, such asa varnish, shellac, or gum applied thereto, or a piece, 0,of tinfoil, and a protector, d, of paper, cloth, or rubber cloth, or apiece of glass. The card, however, may itselzlf be of water-proof paperor other materla The card is held in place in the brick or block byfilling in the recess with cement or other plastic substance, D, thatwill solidify. This filling may be of water or moisture proof matter.

. The card is provided, say at one or more of its corners, with indexes,or printers fists, c, pointing in a single direction, so that the brickor block should be laid in such position as that the indexes will pointaright for the advertiser. If the advertisement be divided, so that itmay be headed for reading from opposite approaches, the indexes will becorrespondingly placed.

The ribs a may be arranged longitudinally upon the bricks, and made thusto serve as division-lines for the advertisement; or they may'runtransversely or otherwise, as fancy or utility dictates. These ribs orbeads serve also to strengthen the bricks.

Bricks or blocks made after my invention will be found a cheap,attractive, and advantageous medium for advertising, as they may be usednot only in proximity to the advertisers location, but elsewhere througha town or city.

When used in pavements already laid, one or more of the paving-bricksmay be removed and my improved advertising bricks or blocks substitutedtherefor.

What I claim is-- The within-described article of manufacture,

viz., a transparent advertising-brick for use in pavements, consistingof the shell A, of the size and shape of ordinary bricks, having theface-protecting ribs or beads a, and an advertisement, b,placed withinsaid shell, and made water or moisture proof, and secured by a fillingof cement or like substance, substantially as shown and specified.
